Resolve SOAP call timeout issues in Adobe Experience Manager Forms
Intermittent SOAP call timeouts can occur in Adobe Experience Manager (AEM) Forms when connecting to external services. To resolve the issue, adjust the JVM heap memory allocation.
Description description
Environment
Adobe Experience Manager (AEM) Forms, all supported versions.
Symptoms
Intermittent timeouts occur when AEM Forms submits XML forms that trigger SOAP calls to external services. These timeouts are often observed during periods of high load or when processing large files. There might be no specific error codes or stack traces.
Cause
Insufficient JVM heap memory can contribute to SOAP call timeout issues.
Resolution resolution
Follow these steps to resolve the issue.
- Review the current JVM heap memory allocation for your AEM Forms instance.
- Increase the JVM heap settings incrementally (for example, from 12 GB to 16 GB) based on observed memory usage and application requirements.
- After updating the JVM settings, perform a planned restart of the AEM Forms service to ensure the changes take effect.
- Monitor the environment for recurrence of SOAP call timeouts after increasing the memory.
- Check whether the AEM Forms service is using the increased JVM resources. Observe whether the issue correlates with large file processing or high-traffic periods.
- If the issue occurs in any AEM Forms environment, consider increasing the resources for those servers as well.
- Verify that SOAP calls complete successfully and that timeouts no longer occur.
